Description

[Technical field]

[0001] The present invention relates to a bathroom sterilization and cleaning system that sprays sterilizing water such as ozone water or hypochlorous acid water into a bathroom. [Background technology]

[0002] A specific example of a bathroom sterilization and cleaning system is, for example, as described in Patent Document 1, which is equipped with an ozone water spraying device that can spray ozone water as sterilizing water into the bathroom. According to this configuration, by spraying the ozone water having a disinfecting effect in the bathroom, various parts such as the walls of the bathroom are disinfected, and the proliferation of mold, bacteria, etc. can be suppressed. It is also possible to remove dirt by spraying the ozone water. Patent documents 2 and 3 describe air conditioners that blow ozone gas into the bathroom. In comparison, the configuration described in Patent document 1, i.e., the configuration of spraying liquid ozone water, not only provides a cleaning effect in which dirt in the bathroom is washed away with the ozone water, but also makes it possible to more effectively bring the ozone in the ozone water into contact with various parts of the bathroom, thereby achieving an excellent sterilizing effect. Ozone water is ozone gas dissolved in water, and OH radicals, which are stronger oxidants than ozone, are generated in the water. Therefore, when ozone water is sprayed, it is possible to obtain a stronger disinfecting effect than when ozone gas is sprayed.

[0003] However, the above-mentioned conventional techniques still have room for improvement, as described below.

[0004] First, there may be areas in the bathroom that are less resistant to ozone. The progress of material deterioration in such areas depends on the product of the concentration of ozone water and the exposure time. For this reason, spraying a large amount of high-concentration ozone water in the bathroom for a long period of time may cause deterioration (discoloration, corrosion, etc.) in the areas in the bathroom. Therefore, it is desirable to appropriately resolve such issues. Secondly, when ozone water is sprayed in the bathroom, ozone gas is liberated from the ozone water. If the ozone gas concentration in the bathroom becomes high, not only will it cause the parts of the bathroom to deteriorate, but the odor specific to ozone will become stronger. Therefore, if a user inadvertently enters the bathroom in such a situation, there is a risk that the user will feel uncomfortable. In addition, there is a risk that high-concentration ozone gas will leak out of the bathroom through a gap in the bathroom door, causing the user to feel uncomfortable due to the odor. It is desirable to appropriately resolve such issues as well. One way to eliminate the above-mentioned concerns is to shorten the time for spraying ozone water. However, it is difficult to eliminate the above-mentioned concerns adequately by simply adopting such a means. This is because ozone water remains in the bathroom even after the spraying of ozone water is finished, and this remaining ozone water acts on the above-mentioned parts of the bathroom for a relatively long time. In addition, ozone gas is liberated from the ozone water remaining in the bathroom and tends to fill the bathroom. In order to eliminate these issues, it is necessary to significantly reduce the amount of ozone water sprayed, but this makes it impossible to properly perform sterilization and cleaning using ozone water.

[0005] The above-mentioned problems are not limited to cases where ozone water is used as the disinfecting water, but may also occur when other types of disinfecting water, such as hypochlorous acid water, are used. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2020-48858 A [Patent Document 2] Japanese Patent Application Publication No. 11-14116 [Patent Document 3] Patent No. 3992942 [Patent Document 4] JP 2019-166278 A Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention was conceived under the circumstances described above, and has an object to provide a bathroom sterilization and cleaning system that can efficiently and appropriately sterilize and clean the bathroom while preventing deterioration of specific parts of the bathroom due to sterilizing water such as ozone water, and preventing the gas concentration, such as liberated gas from the sterilizing water, in the bathroom from becoming excessively high. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides the following technical solutions.

[0009] The bathroom sterilization and cleaning system provided by the present invention is a bathroom sterilization and cleaning system comprising: a sterilization water spraying device capable of executing a sterilization water spraying step of spraying sterilized water into the bathroom to sterilize the bathroom; a non-sterilized water spraying device capable of executing a sterilization water rinsing step of spraying non-sterilized water into the bathroom after the sterilization water spraying step is completed to rinse away the sterilized water remaining in the bathroom; and a ventilation device capable of executing a bathroom ventilation step of exhausting air from the bathroom to the outside. When a single bathroom sterilization and cleaning process is performed as a bathroom sterilization and cleaning process, a set of multiple operation steps including the sterilization water spraying step, the sterilization water rinsing step after the sterilization water spraying step is completed, and the bathroom ventilation step after the sterilization water rinsing step is completed is considered as one set, and the multiple operation steps are configured to be executed repeatedly in multiple sets.

[0010] According to this configuration, the following effects can be obtained. That is, since the disinfecting water spraying process is repeated multiple times, the amount and duration of disinfecting water sprayed into the bathroom when one disinfecting water spraying process is performed can be set relatively small, and the degree to which each part of the bathroom is exposed to the disinfecting water during the disinfecting water spraying process can be reduced. In addition, since the disinfecting water washing-out process and the subsequent bathroom ventilation process are performed each time the disinfecting water spraying process is completed, it is possible to prevent most of the disinfecting water sprayed into the bathroom from remaining in the bathroom for a relatively long period of time, and even if free gas (e.g., ozone gas, etc.) or volatile gas is generated from the disinfecting water, this gas can be quickly exhausted to the outside of the bathroom. If the amount of disinfecting water sprayed into the bathroom performed in one disinfecting water spraying process is set to a small amount, it is also possible to shorten the time for the disinfecting water washing-out process and the bathroom ventilation process accordingly. As a result, the problem of deterioration of parts of the bathroom that are less resistant to the disinfecting water due to the disinfecting water (and its free gas, vaporized gas, etc.) is appropriately suppressed. In addition, the bathroom is prevented from becoming an atmosphere with excessively high concentrations of free gas and volatile gas from the sterilized water, and the risk of free gas and volatile gas causing discomfort to the user can be appropriately eliminated. On the other hand, since the disinfecting water spraying process is performed multiple times, even if the amount of disinfecting water sprayed and the spraying time in one disinfecting water spraying process are set relatively small, the total amount of disinfecting water sprayed and the spraying time (the product of concentration and exposure time) can be sufficiently ensured to reach the CT value (Concentration-Time Value) at which bacteria and viruses are inactivated, for example. Therefore, it is possible to achieve excellent disinfecting and cleaning efficiency in the bathroom.

[0011] In the present invention, the bathroom disinfection and cleaning process is preferably configured to end when a predetermined number of sets of the plurality of operational steps have been executed.

[0012] According to this configuration, after the bathroom sterilization and cleaning process is started, This makes it easier to control when to end the process. More preferably, the "multiple sets" refers to the number of times that the total amount of disinfectant water sprayed and the spray time (product of concentration and exposure time) reach the CT value at which bacteria or viruses are inactivated. This can be determined by testing or simulation, taking into account the actual amount, concentration, and spray time of disinfectant water sprayed in one disinfectant water spraying process for a bathroom of a typical structure and size.

[0013] In the present invention, the bathroom ventilation process is preferably configured to be performed after the disinfecting water rinsing process is completed, and also during the disinfecting water spraying process and the disinfecting water rinsing process.

[0014] With this configuration, it is possible to more reliably prevent the bathroom from becoming an atmosphere with a high concentration of free gas and volatile gas from the sterilized water.

[0015] In the present invention, the bathroom ventilation step is preferably configured so that the ventilation air volume is greater after the disinfecting water rinsing step is completed than during the disinfecting water spraying step and during the disinfecting water rinsing step.

[0016] According to this configuration, the free gas and volatile gas from the sterilized water are exhausted to the outside of the bathroom more thoroughly after the sterilized water washing-out process is completed, so that the bathroom is more effectively prevented from becoming an atmosphere of high concentration of the free gas and volatile gas from the sterilized water. Also, there is no need to rotate the ventilation device unnecessarily at high speed for a long time, which is also preferable in terms of reducing the running cost of the system.

[0017] In the present invention, it is preferable that the present invention further includes a hot air blower capable of blowing hot air into the bathroom, and after the bathroom sterilization and cleaning process is completed, a bathroom drying process is possible in which the bathroom is dried by blowing hot air from the hot air blower.

[0018] With this configuration, after the bathroom sterilization and cleaning process is completed, remaining sterilized water and its free or volatile gases can be eliminated more proactively and quickly, allowing the user to enter the bathroom quickly without feeling uncomfortable.

[0019] In the present invention, it is preferable that when the disinfectant water spraying step of the bathroom disinfection cleaning process is interrupted midway after the disinfectant water spraying step has been started, the disinfectant water rinsing step and the bathroom ventilation step are forcibly executed after the interruption, and then the bathroom disinfection cleaning process is terminated.

[0020] According to this configuration, when the disinfecting water spraying process is stopped midway, it is possible to appropriately prevent a large amount of disinfecting water from remaining in the bathroom, or the bathroom from being filled with free gas and volatile gas from the disinfecting water. Therefore, it is more preferable to prevent parts of the bathroom that are less resistant to the disinfecting water from being deteriorated due to the disinfecting water, its free gas, vaporized gas, etc., and to prevent the bathroom from becoming an atmosphere with a high concentration of these gases.

[0021] In the present invention, it is preferable that the apparatus is configured to be capable of carrying out other operational processes different from the bathroom sterilization cleaning process, and that when, after the sterilizing water spraying process of the bathroom sterilization cleaning process has been started, an operational command is received to execute the other operational process during the sterilizing water spraying process, the sterilizing water spraying process is interrupted, and then the sterilizing water rinsing process and the bathroom ventilation process are forcibly executed before the other operational process is started.

[0022] According to this configuration, the following effects can be obtained. That is, when an operation command to execute another operation process is given during the disinfectant water spraying process, the disinfectant water spraying process is interrupted, but the disinfectant water washing-out process and the bathroom ventilation process are subsequently forcibly executed, so that it is possible to appropriately avoid a situation in which a large amount of disinfectant water remains in the bathroom and the bathroom becomes filled with free gas or vaporized gas of the disinfectant water. In addition, since the other operation process is started after the disinfectant water washing-out process and the bathroom ventilation process are executed, for example, the user does not need to operate a switch again to execute the other operation process, which is convenient.

[0023] In the present invention, preferably, the device further comprises a display means capable of distinguishing between a period when the bathroom disinfection cleaning process is being performed and a period when the bathroom disinfection cleaning process is not being performed.

[0024] With this configuration, the user can easily and accurately determine whether the bathroom sterilization and cleaning system is currently performing the bathroom sterilization and cleaning process by looking at the display provided by the display means, which is convenient.

[0025] Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings. [Brief description of the drawings]

[Figure 4] 3 is a flowchart showing another example of the operational procedure executed in the bathroom disinfection and cleaning system shown in FIGS. 1 and 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0028] The bathroom sterilization and cleaning system SY shown in Figures 1 and 2 is configured to include a bathroom drying device A. Bathroom drying device A is configured by combining a main body A0 installed on the ceiling 10 of bathroom 1, for example above bathtub 11, with a separate remote control 2. A sterilized water / non-sterilized water sprayer 4, which will be described later, is built into main body A0. Here, the disinfected water / non-sterilized water spraying device 4 is a device in which the "disinfected water spraying device" and the "non-sterilized water spraying device" of the present invention are integrated into one device. In this embodiment, "ozone water" is used as the disinfected water, and "tap water" is used as the "non-sterilized water". The disinfected water / non-sterilized water spraying device 4 can selectively spray either ozone water or tap water into the bathroom 1.

[0029] Bathroom drying apparatus A is configured to receive a supply of hot water from hot water supply apparatus 8. Hot water supply apparatus 8 is capable of supplying hot water to bathtub 11 via piping 80, and also has a general hot water supply function to the kitchen, etc., and is equipped with bathroom remote control 81A and kitchen remote control 81B.

[0030] The main body A0 of the bathroom drying device A comprises a blower fan 30 (also called a circulation fan), a heat exchanger 31 for heating air, a ventilation fan 32, an ozone water sprayer 4, a control unit 5, and a housing 34 that covers all of these parts.

[0031] Blower fan 30 is capable of drawing in air from bathroom 1 through air inlet 35a provided on the underside of housing 34 and blowing the air into bathroom 1 via louver 36 provided at the air outlet. Heat exchanger 31 heats the air drawn into blower fan 30 through air inlet 35a, and heated hot water can be supplied to heat exchanger 31 from water heater 8 as a medium for this heating. When blower fan 30 is driven, heated hot water is supplied from water heater 8 to heat exchanger 31, and the air drawn through air inlet 35a is heated, and hot air is blown into bathroom 1 through louver 36. During the bathroom drying process of bathroom drying device A, the above-mentioned blowing of hot air and ventilation by ventilation fan 32 are performed in parallel. When the supply of heated hot water to heat exchanger 31 is stopped, unheated air (unheated air) can be blown from louvers 36 to bathroom 1. The orientation of louvers 36 can be changed by a motor (not shown), and the air blowing angle when blowing air into bathroom 1 can be changed as appropriate.

[0032] Ventilation fan 32 is a fan for exhausting air (including ozone gas, described later) in bathroom 1 to the outdoors. When ventilation fan 32 is operated, air in bathroom 1 is sucked into housing 34 through air inlet 35a, enters the installation area of ​​ventilation fan 32, and is exhausted to the outdoors through exhaust outlet 37. Ventilation fan 32 corresponds to a specific example of a "ventilation device" according to the present invention. The rotation speed of ventilation fan 32 is variable, so that the amount of ventilation air in bathroom 1 can be increased or decreased.

[0033] As described above, the disinfected water / non-disinfected water spraying device 4 is a device that can selectively spray either ozone water as disinfected water or tap water as non-disinfected water, and includes a water supply pipe section 60 that receives tap water from the outside, an on-off valve Vb such as an electromagnetic valve provided in the middle of the water supply pipe section 60, an ozone water generator 42 provided downstream of the valve, and a nozzle 43 for spraying provided at the end of the water supply pipe section 60. The ozone water generator 42 is a type that generates ozone by electrolysis of water using electrodes, for example. When the on-off valve Vb is set to an open state and the ozone water generator 42 is driven on, the ozone water generated by passing through the ozone water generator is sprayed from the nozzle 43 toward the bathroom 1. The ozone water is sprayed toward, for example, almost the entire area of ​​each side wall surface 12 of the bathroom 1 except for the portion near the upper end, the bathtub 11, and almost the entire area of ​​the floor surface 13. When the ozone water generator 42 is turned off, tap water can be sprayed from the nozzle 43 instead of the ozone water.

[0034] Control unit 5 is configured using a microcomputer etc., and controls the operation of each part of bathroom drying device A, causing bathroom 1 to perform drying operations and the like, as well as causing bathroom 1 to perform a sterilization cleaning process, as described below. When this bathroom sterilization cleaning process is performed, a set of multiple operation steps is performed in sequence, including a sterilization water spraying step of spraying ozone water from nozzle 43, a sterilization water rinsing step of spraying tap water from nozzle 43, and a bathroom ventilating step after completion of the sterilization water rinsing step, and then these multiple operation steps are repeated in multiple sets, the details of which will be described later.

[0035] The control unit 5 is capable of wireless data communication with the remote control 2 via the communication unit 50. The remote control 2 is, for example, portable, and includes a communication circuit (not shown) for wirelessly communicating with the control unit 5 via the communication unit 50, a plurality of operation switches 20 for issuing various operation commands, and a display unit 21. The bathroom sterilization and cleaning system SY also includes indicator lamps 22a, 22b that light up or flash while the bathroom sterilization and cleaning process is being performed and while the bathroom drying process is being performed, respectively. The indicator lamp 22a corresponds to an example of the "display means" of the present invention. The remote control 2 may be configured for wired communication instead of wireless communication.

[0036] Next, an example of an operational process performed in the bathroom sterilization and cleaning system SY will be described with reference to the flow chart shown in Fig. 3. The operation of the system will also be described.

[0037] In the bathroom sterilization and cleaning system SY of this embodiment, when an operation is performed using, for example, remote control 2 to start the bathroom sterilization and cleaning process, indicator lamp 22a lights up to indicate that the bathroom sterilization and cleaning process is being performed, and a sterilization water spraying process is started in which ozone water is sprayed from nozzle 43 into bathroom 1 (S1: YES, S2, S3). At that time, a bathroom ventilation process is also started by driving ventilation fan 32. According to this operation process, each part of bathroom 1 is sterilized and cleaned using ozone water. Bathroom ventilation is also performed, so that an excessive increase in the ozone concentration in bathroom 1 is appropriately prevented. Thereafter, when the spraying time or spraying amount of the sterilized water (ozone water) reaches a predetermined value, the sterilized water spraying process ends at that point (S4: YES, S5).

[0038] After the disinfecting water spraying process is completed, a disinfecting water rinsing process is started in which tap water is sprayed from nozzle 43 into bathroom 1 (S6). In this disinfecting water rinsing process, disinfecting water that has adhered to and remained in various parts of bathroom 1 is washed away and can be drained to the outside through the bathroom 1 drain. This prevents disinfecting water from adhering to various parts of bathroom 1 for an unnecessarily long period of time. The disinfecting water rinsing process ends when the spraying time or amount of tap water reaches a predetermined value (S7: YES, S8).

[0039] When the sterilizing water rinsing process is completed, the rotation speed of ventilation fan 32 is increased above the normal speed up to that point, and the bathroom ventilation process continues (S9). Ozone gas is liberated from the ozone water that has been sprayed into bathroom 1, and this ozone gas remains in bathroom 1. The above-described operation makes it possible to efficiently and quickly exhaust such ozone gas to the outside of bathroom 1. When the bathroom ventilation time or ventilation volume after the sterilizing water rinsing process is completed, the bathroom ventilation process ends (S10: YES, S11).

[0040] However, in this embodiment, when a set of multiple operation steps consisting of the sterilizing water spraying step, the sterilizing water rinsing step, and the subsequent bathroom ventilation step is taken, the control unit 5 judges whether the number of times the operation steps have been performed (the number of sets) has reached a predetermined number of times (for example, two times) (S12). If the number of times the operation steps have been performed has not reached the predetermined number of times, the operation steps are repeated again (S12: NO). In this way, if the number of times the operation steps have been performed has not reached the predetermined number of times, there is no need to temporarily end the bathroom ventilation step (step S11 can be omitted), and the ventilation fan 32 can be left rotating thereafter. When the second sterilizing water spraying step is started, control is executed to return the rotation speed of the ventilation fan 32 to the original normal speed. On the other hand, unlike the above, when the number of times that the multiple operating steps consisting of the sterilizing water spraying step, the sterilizing water rinsing step, and the subsequent bathroom ventilation step have been performed reaches a predetermined number of times, the bathroom sterilization cleaning process is terminated and the indicator lamp 22a is turned off (S12: YES, S13).

[0041] According to the above-mentioned series of operational controls, the disinfectant water spraying process is repeated in a predetermined number of small portions, so that it is possible to set the amount and duration of ozone water sprayed into bathroom 1 relatively small when one disinfectant water spraying process is carried out. This makes it possible to reduce the degree to which each part of bathroom 1 is exposed to ozone water during the disinfectant water spraying process. Furthermore, each time the disinfectant water spraying process is completed, a disinfectant water rinsing process is carried out to wash away the ozone water using tap water, and a subsequent bathroom ventilation process is carried out, so that it is possible to prevent much of the disinfectant water sprayed into bathroom 1 from remaining in the bathroom for a relatively long period of time. Furthermore, the ozone gas liberated from the ozone water can be quickly exhausted to the outside of bathroom 1. Furthermore, Furthermore, if the amount of ozone water sprayed into the bathroom 1 during each disinfecting water spraying process is reduced, the disinfecting water rinsing process and the bathroom ventilation process can be shortened accordingly. This appropriately prevents parts of the bathroom 1 that are less resistant to ozone water from deteriorating due to ozone water (and ozone gas). It also appropriately prevents the bathroom 1 from becoming an atmosphere with a high concentration of ozone gas, making it possible to appropriately eliminate the risk of ozone gas causing discomfort to the user. On the other hand, since the disinfecting water spraying process is performed multiple times, even if the amount of ozone water sprayed and the spraying time in each disinfecting water spraying process are set relatively small, the total amount of ozone water sprayed and the spraying time (the product of the concentration and the exposure time) can be sufficiently secured so as to reach the CT value at which bacteria and viruses are inactivated, for example. Therefore, it is possible to achieve excellent disinfecting and cleaning efficiency in the bathroom 1.

[0042] After the bathroom sterilization and cleaning process is completed, the louvers 36 start blowing warm air into the bathroom 1, and the bathroom drying process is carried out (S14). In this case, the indicator lamp 22b is turned on to indicate that the bathroom drying process is in progress (S15). This bathroom drying process makes it possible to ensure that almost no ozone water, ozone gas, or tap water remains in the bathroom 1. When the bathroom 1 has dried to a predetermined level (such as when the humidity has dropped to a predetermined value, or the rate of change in humidity has dropped below a predetermined level), the bathroom drying process ends at that point, and the indicator lamp 22b is turned off (S16: YES, S17).

[0043] The disinfected water / non-disinfected water spraying device 4 in this embodiment is configured to be a disinfected water spraying device and a non-disinfected water spraying device. Therefore, compared with the case where these two devices are manufactured separately, it is possible to simplify the overall configuration and reduce the manufacturing cost. In addition, since ozone water and tap water are sprayed from the same nozzle 43, it is also possible to match the spray area of ​​the ozone water with the spray area of ​​the tap water for washing away the ozone water, thereby improving the washing away effect of the ozone water.

[0044] In the bathroom sterilization and cleaning system SY of this embodiment, the operation control as shown in FIG. 4 can also be executed.

[0045] Note that steps S1 to S5 in Fig. 4 are the same as those in Fig. 3. Although steps S6 to S17 in Fig. 3 are omitted in Fig. 4, these steps S6 to S17 can also be executed. First, during the disinfectant water spraying process of S3, when the spraying time or amount of disinfectant water (ozone water) into the bathroom 1 has not yet reached a predetermined value, an operation to stop the bathroom disinfection cleaning process may be performed, for example, using the remote control 2 (S4: NO, S21: YES). In this case, the disinfectant water spraying process is immediately ended, but thereafter, the disinfectant water rinsing process and the bathroom ventilation process are executed in sequence (S22, S23).

[0046] Such operational control makes it possible to appropriately prevent a large amount of ozone water from remaining in bathroom 1 or for ozone gas to fill bathroom 1 if the sterilizing water spraying process is stopped midway. This is therefore even more preferable in preventing parts of bathroom 1 that are less resistant to ozone water from being deteriorated by ozone water or ozone gas.

[0047] Instead of the operation to stop the disinfecting water spraying process in step S21, an operation command may be issued to execute another operation process (such as heating the bathroom 1) different from the bathroom disinfection cleaning process (S21: NO, S24: YES). In this case, when the operation command is issued, the disinfecting water spraying process ends, and the disinfecting water rinsing process and the subsequent bathroom ventilation process are executed in sequence (S25, S26). After that, the other operation process is started ( S27).

[0048] According to this type of operation control, although the disinfectant water spraying process is interrupted, the disinfectant water washing-off process and the bathroom ventilation process are subsequently forcibly performed, appropriately preventing a large amount of ozone water from remaining in bathroom 1 and a large amount of ozone gas from filling bathroom 1. Furthermore, after the disinfectant water washing-off process and the bathroom ventilation process are performed, the other operation process is started, which is convenient and does not require the user to take the trouble of operating a switch again to perform the other operation process.

[0049] The present invention is not limited to the above-described embodiment. The specific configuration of each part of the bathroom disinfection and cleaning system according to the present invention can be freely designed and modified in various ways within the intended scope of the present invention.

[0050] In the above embodiment, one bathroom sterilization cleaning process is a set of a sterilization water spraying process, a sterilization water rinsing process, and a subsequent bathroom ventilation process, and these are performed a predetermined number of times (for example, twice), but the number of times may be any number of times, and the specific value is not limited. As mentioned above, the predetermined number of times is preferably the number of times that the total amount of sterilization water sprayed into the bathroom and the spraying time (the product of the concentration and the exposure time) reach the CT value at which bacteria and viruses are inactivated.

[0051] In the above embodiment, the bathroom ventilation step is performed during the disinfectant water spraying step and the disinfectant water rinsing step, but the present invention is not limited to this. The bathroom ventilation step may be performed after the disinfectant water rinsing step is completed.

[0052] The disinfectant water is not limited to ozone water as long as it is a liquid that exhibits a disinfecting effect. For example, other types of disinfectant water, such as hypochlorous acid water, can also be used. The non-sterilized water is water for washing away the sterilized water, and is not limited to tap water. For example, water other than tap water, such as well water pumped up by a pump, can also be used.

[0053] In the above embodiment, the sterilized water / non-sterilized water spraying device 4 is provided, and the sterilized water spraying device and the non-sterilized water spraying device are integrated, but the present invention is not limited to this. The sterilized water spraying device and the non-sterilized water spraying device may not be integrated, and may be configured as separate devices. The disinfectant water spraying device (ozone water spraying device) may be configured to spray disinfectant water into the bathroom, and the specific method of generating disinfectant water and the concentration of specific components in the generated disinfectant water are not limited. The number of nozzles for spraying disinfectant water is not limited to one, and multiple nozzles may be used, and the specific number of nozzles is not important. Moreover, the disinfectant water may be sprayed intermittently, for example, at a predetermined short period, instead of continuously.

[0054] In the above embodiment, the sterilized water / non-sterilized water sprayer 4 (sterilized water sprayer and non-sterilized water sprayer) is incorporated into the bathroom drying device equipped with a blower fan and a ventilation fan, but the present invention is not limited to this. It is also possible to configure the sterilized water sprayer and non-sterilized water sprayer to be provided in a location separate from the bathroom drying device. The specific configuration of the ventilation device according to the present invention is not limited. The display means in the present invention is not limited to an indicator lamp, but may be a liquid crystal display panel or the like. [Explanation of symbols]
